Title: Wenzhen Li: Innovator in OFDM Systems
Introduction
Wenzhen Li is a notable inventor based in Singapore, recognized for his contributions to the field of signal processing, particularly in Orthogonal Frequency Division Multiplexing (OFDM) systems. He holds three patents that showcase his innovative approaches to improving signal equalization and demapping techniques.
Latest Patents
One of Wenzhen Li's latest patents is titled "System and method for performing LS equalization on a signal in an OFDM system." This invention describes a system that includes a receiver stage for receiving a modulated signal, a demodulation stage for producing a demodulated signal, and a channel estimation stage that processes the demodulated signal to provide an output signal corresponding to a channel frequency response. The equalization stage utilizes this channel state information to enhance the demodulated signal, resulting in an equalized output.
Another significant patent is "Method, apparatus and receiver for demapping dual carrier modulated COFDM signals." This patent outlines a method for demapping signals by normalizing an estimated channel state information signal and determining weighting factors for equalization. The process culminates in linear demapping of the weighted input signal, enhancing the efficiency of COFDM signal processing.
